Firework Rocket Pack

This would be a new transportation item similar to the Elytra. It would go on the players chestplate area and allow the player to fly for a bit. It would be made with 2 Firework Rockets & 5 String. Depending on the flight Duration of the Firework Rocket used it would have different durability. Each second the pack is used would equal 1 durability. For example a Firework Rocket Pack with Flight Duration 1 would have 30 durability or 30 seconds of flight. Flight Duration 2 would be 60 durability and Flight Duration 3 would be 90 durability.
